DRIP PAN FOR FLUSH TANKS Filed June 17, 1948 AT TOR NEYS Patented June3, 1,952

1 Claim.

.11 l ,.'My .invention .refers A.to .drippans :for v.ilush vtanks and ithas for its primary. object-to. provide a pan having adjustable seatsfor the supply and ush pipesv 'of a tank, whereby compensation ishadzfortvariations that areiafzound in the1;position tofasaid pipes,with .reference'rtoythe tankbottom. 'L'Ihe three pointA suspension`set" bolt attaching vzineansfor.thepan to the ushxpipe isfsimilar tothatushowninmyo -pendingpatent application #8,380, dated .February l1.4,.1948.

The specic object of my present invention is to provide compensatingplates for the pipe openingsxin 'a pan, Wherebythe supply pipe may beboxed, 'irrespective of its lateral or transverse position, withreference to the tank bottom, and an anchor boxing plate assemblage forthe ush pipe, irrespective of its transverse position rela tive to saidtank bottom.

A further object of my invention is to provide a. transverselyadjustable boxing plate for the ush pipe associated with the pan, havingthree point suspension radially disposed bolts for anchoring said pan.

With the above and other objects in view, which will appear as thedescription proceeds, the invention resides in the novel construction,combination and arrangement of parts, substantially as hereinafterdescribed, and more particularly defined by the appended claims, itbeing understood that such changes in the precise embodiment of theherein disclosed invention may be made as come within the scope of theclaim.

In the accompanying drawings is illustrated one complete example of thephysical embodiment of the present invention constructed according tothe best mode so far devised for the practical application of theprinciples thereof.

In the drawings:

Fig. 1 represents a sectional elevation of a drip-pan attaching means toa tank flush pipe, embodying the features of my invention, the sectionbeing indicated by line I--I of Figs. 2 and 3 of the drawings.

Fig. 2 is a longitudinal sectional view through the same, the sectionbeing indicated by line 2-2 of Fig. 3.

Fig. 3 is a plan view of the same, partly in section as indicated byline 3 3 of Fig. 2; and

Fig. 4 is a detail cross sectional view through the boxing assemblage ofthe flush pipe, the section being indicated by line 4--4 of Fig. 3.

Referring by characters to the drawings, A indicates a ush tank, havingdepending from its bottom a flush pipe B and a supply pipe C.

Anchored under the bottom of the tank is an Aupstandingribbedzrdripe-pan 'I ,f'having aifribbed or fnanged slotted `opening 2,:extending fifromone edgethereofffand associatedwiththeasupplyzpipe C,the said opening being of a materiallyigreater cross lvsectionalareajthantheipipa I :'Aseconjd upstandingru fshapednanged opening 3 alsoextends fromithemear edge-:ofthezpanrand its edge flange terminates withan inwarldly @extended wing .14, having a curve'd f throatrfabout :11.0fthe# ushlpipe and. :straight .leg;.extensions5the1.e

from. The vswing :extensions fareaformed zwithfslots andftted :over,asaid wing` extensions-.israfboxing plate ,1 the 'samer-havingdownturned angsrf 215 which engage :.theziiangesfof the` associatedfpanopening and said boxing plate is formed with an open throat extendinginwardly from its rear edge terminating in an enlarged circular opening.An upturned ange 'I extends about the circular edge of the opening.

The upturned flange I carries a centrally positioned upstanding ear 1',which adjustably receives a threaded set bolt 8. Depending from thewalls of the circular opening adjacent to the throat and on oppositesides of the ear 'I' are ears 9 and these ears adjustably receivethreaded set bolts I0. The bolts I0 in conjunction with the set bolt 8form a three-point suspension anchor for the pan, the bolts beingthreaded into tight engagement with the flush pipe B.

The boxing plate 6 carries a pair of depending bolts I I, which boltspass through the Wing slots 5 and are secured by thumb nuts, whereby thepan can be adjusted backwardly and forwardly.

As best indicated in Figs. 2 to 4 inclusive, the throat portion of theboxing plate is fitted with an adjustable extension plate I2, havingdownturned edge flanges in slidable engagement with the throat portionsof the boxing plate.

The adjustable extension plate I2 is also provided with an upstandingcircular hanged recess I2', which recess, when the parts are inposition, completes the circular throat recess of the boxing plate. Thisextension plate I2 serves to close up the rear portion of the opening 3and if said extension plate is not of sufcient length, a secondextension plate I3 may be lapped over the same and in slidable uniontherewith.

Thus the depth of the ush tank drip-pan opening is adjustable, wherebysaid opening is closed from end to end. Due to the transverse adjustmentof the boxing plate, the position of the ilush pipe is accommodated forthe three point anchor means.

Referring to the slotted opening 2 of the drippan, which is associatedwith the supply pipe C, I provide a boxing plate I4, having downturnedflanges which are spaced from the anges of the opening 2, and also saidboxing plate is provided with a throat I5, having an upturned flange,which is centered about the supply pipe. By employing a boxing plate ofthis type, it will be noted that it may be adjusted longitudinally andalso laterally, whereby it will properly jacket the supply pipe lC,irrespective of its position, with reference to the ush pipe.

In some instances the throat of the boxing plate I 4 may be providedwith a laterally disposed strip, not shown, for closing the throatopening.

It will be noted. as illustrated in Fig. 1 of the drawings, that the panis of standard type and is slightly forwardly inclined and provided witha drain nipple D.

It is to be noted that the pair of set bolts engaging the flush pipe areshown in a different plane from the companion single set bolt, wherebydue to the obliquely disposed grip upon the flush pipe there is littletendency for slippage of the drip-pan.

While I have specifically dened structural details, it is understoodthat I may vary the same within the scope of the claim.

I claim:

A drip-pan for flush tanks having an open pipe receiving slot extendinginwardly from one edge thereof, the edges of said slot being providedwith an upstanding flange having an inwardly extending wing, said wingbeing provided with longitudinally extending slots, a boxing plate ttedover the wing and having opposite down-turned flanges engaging theflange of the slot in the pan and a fiat surface having an open throatextending inwardly from the rear edge thereof and terminating in anenlarged circular opening, an upstanding flange surrounding the circularedge of the opening for engaging about a pipe, an upstanding centrallydisposed ear carried by the iiange, a set bolt carried by said ear, apair of depending ears disposed on each side of the central ear adjacentto the front of the circular opening at the junction with the throat andcarried by the sides of the opening, set bolts carried by said pair ofears for engaging a pipe below the rst mentioned set bolt, and thumbnuts and bolts carried by said boxing plate and received in the slots ofthe wing, whereby the pan can be adjusted back and forth on the boxingplate.
